Overview
Claude is Anthropic's conversational AI app, available on Web, iOS, Android, and desktop. It is favored by developers and knowledge workers for its strengths in coding, long-context reasoning, and safety. The flagship is Claude Opus 5 (released July 24, 2026), which is the default model on Claude Max. The 1M token context window is available at standard pricing.
Latest / Key Features
Claude Opus 5 / Sonnet 5
Pro and higher plans run on Opus 5 and Sonnet 5. Opus 5 pairs a 1M-token context window with an xhigh reasoning-effort mode and is priced at $5 in / $25 out per million tokens. Sonnet 5 runs $2 in / $10 out — a level Anthropic originally framed as introductory pricing through August 31, 2026, then made permanent in August 2026.
Cowork (Agentic Feature)
Launched for Max on January 12, 2026, and extended to Pro four days later. Cowork lets Claude autonomously complete multi-step tasks such as organizing research files, analyzing data across multiple documents, and coordinating project workflows. In August 2026 it expanded to web, iOS, and Android — sessions run in the cloud, so work continues after the device goes offline.
Pay-as-You-Go Overages
Pro, Max 5x, and Max 20x all support continuing past plan limits at API-standard pricing, with user-set monthly caps.
Artifacts / Projects
Artifacts renders code, docs, and mini apps in a live preview during chat. Projects persists long-running context and files. Both are available on Pro and above. Artifacts can now call your MCP connectors to pull live data, so a shared URL re-renders with fresh values every time it is opened.
Voice mode on the top-tier models
Since July 24, 2026, Claude's voice mode runs on Anthropic's most capable models across iOS, Android, Web, and Desktop instead of a lightweight tier, bringing audio conversation quality up to the same level as text on every platform.
Claude Code Integration
Max plans ($100 / $200) include full access to Claude Code, the terminal-based autonomous coding agent that understands entire repositories, edits across files, and runs commands on its own.
Plans & Pricing
Pro is $20/month (about $17/month billed annually) and Max comes in $100 and $200 tiers, with Opus 5 as the default model on Max.
